----------------------------------------
Summary: Throw ExecutionException for E() syntax
Key: TINKERPOP-2910
URL: https://issues.apache.org/jira/browse/TINKERPOP-2910
Project: TinkerPop
Issue Type: Bug
Components: driver, server
Affects Versions: 3.6.2
Environment: - TinkerGraph Version: 3.6.2
- Operating system: macOS 13.2.1
- API/Driver: Java
Reporter: Zeyang Zhuang
I first randomly create a graph. Then when I run the following query:
`g.E().outV().bothE('el0','el2','el1','el3').as('a').E().where(__.and(__.order().by(desc))).as('b').select('a').where('a',eq('b'))`
is thrown with an exception. I think this query is syntactically correct, but
I keep triggering this kind of problem. I generate the query based on the rule
which can be refered from:
https://stackoverflow.com/questions/48067834/gremlin-intersection-operation.
Following this instruction, I think it's allowed to generate this kind of
queries.
*Expected behavior:*
No exception should be expected to throw. Or futher messages or prompts should
be thrown.
*Actual behavior:*
A `java.util.concurrent.ExecutionException` is thrown. And I'm not really sure
whether this problem should happen so I report this. I succeed this kind of
collection transition when replacing `g.E()` with `g.V()`. So I guess there's
some problems of `g.E()` syntax. I report just in case
```
TinkerGraph exception :
java.util.concurrent.ExecutionException:
org.apache.tinkerpop.gremlin.driver.exception.ResponseException: No signature
of method:
org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.DefaultGraphTraversal.E()
is applicable for argument types: () values: []
Possible solutions: is(java.lang.Object), by(groovy.lang.Closure),
use([Ljava.lang.Object;), use(java.lang.Class, groovy.lang.Closure),
use(java.util.List, groovy.lang.Closure), any()
```
*Steps to reproduce:*
We create a graph with 10 nodes and 20 edges. We try to make it clear to
reproduce the bugs, **hope** to not cause much inconvenience to your reviewing,
but we believe the problem does exist.
Following the following graph data generation query, we can reproduce the bugs:
